Let's start with the iPhone. Go to Settings > Mail > Accounts > [name of email] > Server Settings.
- Does it show POP or IMAP after Incoming Mail Server?
- What is listed as the Host Name?
When adding the account, it usually defaults to IMAP, but it you are getting POP instead, there is a trick you can do to specify a different email type. Add the account again and intentionally enter the wrong Password when setting it up. It will fail to add the account, but you should see an option to choose either "IMAP" or "POP" on the top of that screen. After you choose POP, enter the correct Password.
Another issue that is common when you receive the message that it is unable to verify the Account Name or Password is the User Name field where you enter your email address. Some companies require the full address including everything after the "@" sign, while others only want the User Name and don't include the "@" or anything after that.
